Definitions
- the present invention relates to a horn switch system for the horn mechanism of a steering wheel of a vehicle or ship, more particularly, to a horn switch system for the steering wheel of a car.
- the conventional practice is to springingly support a pad on the top center portion of the steering wheel for activation of a horn switch by hand depression.
- This type of pad has a plurality of pad legs at suitable positions on its inner face.
- the legs fit into and engage with pad leg receivers on a contact plate positioned under the pad.
- a compressed spring is interposed between the contact plate and a boss plate positioned beneath the same around a spacer, which supports the contact plate at a different position from the pad leg receiver piece. Therefore, if the pad is depressed, the pad legs press against the contact plate at the positions of the pad leg receivers. The contact plate is pressed down against the compressed spring force along the spacers, whereupon the terminal of the contact plate comes into electrical contact with the boss plate.
- the pad mounting portion and contact plate supporting portion are different in position on the contact plate, even when the two portions are arranged close together, space is required for the two portions.
- the contact plate is a thin plate made light in weight, so, depending on the distance between the position of the pressing action of the pad, that is, the pad mounting position, and the position of the pushing of the contact plate, that is, the point of the pushing up action of the spring (spacer position), a bending action will work on the contact plate at the time of pad depression obstructing smooth up-down movement of the pad.
- the contact stroke of the horn becomes unstable due to the bending action of the contact plate.
- a steering wheel horn switch system including a pad mounted in a steering wheel and having a pad leg; a pad leg receiver for the pad leg; a pushup spring arranged concentrically with the pad leg receiver and against whose force the pad leg receiver is pushed down; a contact plate with a terminal; and an electrode plate with which the terminal of the contact plate comes into electrical contact when the pad is depressed and thus the pad leg receiver is pushed down.
- the pad leg receiver (or receivers) may be a cylindrical body having on its inner circumference a projecting engagement portion for engaging with a projecting portion of the pad leg extending from beneath the pad.
- the cylindrical body may be fixed at its bottom end to the contact plate and support the pad portion at its top.
- a coil spring arranged concentrically with the cylindrical body and around a spacer may be used to bias the pad leg receiver in a direction away from the electrode plate (upper direction).
- steering wheel horn switch system including a pad mounted in a steering wheel and having a pad leg; a pad leg receiver for the pad leg; a mounting boss (1) in which the pad leg receiver is inserted; a contact plate abutting against the bottom of the pad led receiver and having a terminal; a contact plate pushup spring interposed between the contact plate and a base plate (10) of the mounting boss concentrically with the pad leg receiver to springingly support the contact plate; and an electrode plate with which the terminal of the contact plate comes into electrical contact when the pad is depressed and thus the pad leg receiver is pushed down.
- the pad leg receiver and the contact plate pushup spring are arranged concentrically, the pressing force against the pad acts concentrically on the spring, so the action of up-down movement of the pad is smooth. Further, less space is used since the switch assembly is in one piece.
- the switch assembly is an integral unit, it can be used for all types of steering wheels.

- the pad P of the steering wheel has, at one portion, a pad leg F having a projecting engagement portion F 1 on its end and ribs L on its inner face.
- a projecting engagement portion 56 is formed on the inner side of a pad leg receiver 105 mounted on the top face of a contact plate 100.
- An electric contact 101 projects from the bottom face of the plate 100.
- a spacer 106 made of an insulating material is screwed on a boss plate B by a screw 104.
- a flange 106' at the top limits the upward movement of the contact plate 100.
- the contact plate 100 is supported springingly against the boss plate B by a coil spring 3 which is interposed, with an insulating material 107, between the contact plate 100 and boss plate B.
- the pad leg F having a branched portion F 0 , is inserted into the pad leg receiver 105. In this way, the pad P is mounted in place by the projecting portion F 1 of the leg and the projecting portion 56 of the pad leg receiver 105.
- FIG. 2 is a side view of a steering wheel horn switch system according to the first embodiment.
- a spacer 6, comprised of a columnar portion 61, upper flange 62, concentric circular projection 63 formed on the flange and central through hole H, is formed by acrylonitrile-butadiene styrene resin (ABS resin).
- ABS resin acrylonitrile-butadiene styrene resin
- the mounting portion on the contact plate 100 which is made of a conductive material, has a hole 102 for receiving the columnar portion 61 of the spacer 6 and has an electrode 101, which projects bent downward near the hole.
- a pad leg receiver 5 carried on the contact plate 100 is shaped, from ABS resin, as a lower cylinder 51 having a slightly larger inner diameter than that of the flange 62 of the spacer 6, an upper cylinder 52 having a smaller diameter than the lower cylinder, a spring support face 55, a projecting engagement portion 56 on its inner face, and a top end 52'.
- the bottom of the coil spring 3 is inserted over the annular projection 63 formed on the top of the spacer 6.
- the top of the spring abuts against the support face 55 formed on the inner face of the pad leg receiver 5.
- the bottom of the pad leg receiver is fixed to the contact plate 100 by a screw S 1 in the state with the spring 3 compressed.
- the screw S 0 is passed into the through hole H of the spacer 6 from above the pad leg receiver 5 and screwed into the boss plate B.
- the projecting portion F 1 of the pad leg F is pressed into the projecting engagement portion 56 of the pad leg receiver.
- the projecting portion F 1 is deformed inward as the branch portion F 0 is compressed.
- the bottoms of the ribs L' formed around the base portion of the leg on the inner face of the pad press down the top 52' of the pad leg receiver 5, whereby the pad leg receiver 5 compresses the coil spring 3, to move down the contact plate 100 and make the electric contact 101 (+ pole) abut against the boss plate B (- pole) to switch on the horn. Since the coil spring 3 is arranged concentrically with the pad leg receiver 5 on the spacer 6, the pad pressing force acts concentrically on the spacer 6, which is a slidingly guided column of the contact plate 100, without any bending moment. Thus, a smooth feeling of operation is obtained.
- the spacer 6 is a single piece formed of plastic, it serves as an electrical insulator, thus eliminating the need for insulation (107 in FIG. 1) for the spring, as used in the prior art.
- the pad leg receiver is cylindrical, it is easy to make it using plastic. The engagement of the projecting engagement portion 56 with the pad leg is facilitated, and the top 52' can receive correctly the pressing force of the pad.
- FIGS. 3A and 3B show an example of use of the horn switch of this embodiment in a steering wheel.
- the contact plate is split into two parts.
- Horn switches of this embodiment are mounted at the upper (in FIG. 3A) short plate.
- Prior art horn switches (of FIG. 1) are used for the lower long plate as shown at the left in FIG. 3B.
- space is created at the middle of the top face of the boss plate B. In that space, the spoke core metal CP extending from the steering wheel W is mounted.
- An auto-drive switch 8 is also attached thereby screw 81.
- the horn switch of this embodiment is assembled to the prior art type of contact plate and boss plate, it can be mounted on a small space, so can be used together with the prior art switches and creates new space on the prior art boss plate or contact plate.
- pad leg receiver 5 which is capped from below by the contact plate 4, made of a conductive material, is inserted into a cylindrical container shaped mounting boss 1 made of an insulating material.
- a compressed coil spring 3 is interposed between the contact plate 4 and a base plate 10 of the mounting boss.
- a screw 2 with a washer 2', comprising an electrode is inserted into a hole H 1 through the center of the base plate 10 of the mounting boss 1.
- the mounting boss 1 is made by ABS resin. It has the base plate 10 and a circular side wall 11 with four equally spaced slits 14 for enabling it to deform and open.
- the upper portion of the side wall 11 is made thicker and has a taper 12 inclined inwardly.
- An annular groove 15 for supporting a spring is provided along the inner side of the side wall 11 on the inner face (top face) of the base plate 10.
- the pad leg receiver 5 is made by ABS resin. It has a lower cylinder 51 and upper cylinder 52. An annular projection 50 is provided with an upper engagement face 54, taper 53, and contact plate supporting face 55 at the center of the outer circumference of the receiver 5. There is further an annular projecting portion 56, for engaging the projecting engagement portion F 1 (FIG. 1) of the pad leg, at center portion of the inner circumference of the receiver 5.
- the contact plate 4 is made by steel plate. It is formed by pressing to a roughly U-like section having a cylinder portion 42. A center hole H 4 is provided in the bottom 43, which bottom serves on a terminal. Also provided are three projecting pieces 44 and one cord connecting piece 41 for engaging with the slits 14 of the mounting boss 1 on the top flange 45.
- the coil spring 3 is made by piano wire and is coiled four times.
- the space between the washer 2' held by the screw 2 and the contact plate bottom face 43, that is, the contact stroke, is set to 1.5 mm.
- the washer 2' is made larger in diameter than the center hole H 4 of the contact plate bottom face 43.
- the sliding action of the taper 12 of the mounting boss 1 and the taper 53 of the pad leg receiver 5 and the opening action of the slits 14 of the circular side wall 11 of the mounting boss 1 facilitate insertion of the pad leg receiver 5 into the mounting boss.
- the spring 3 is held stably between the annular groove 15 of the base plate 10 and the flange 45 of the contact plate 4 and since the base plate 10 is an insulator, no insulation is required for the spring like in the prior art switch (107 in FIG. 1).
- the electrode plate is the washer 2', which has a larger diameter than the center hole H 4 of the contact plate, the switch can be mounted to the boss plate B simply by a single screw 2.

- the spring supporting disc 7 is inserted on the electrode plate 20 of the bottom of the mounting boss 1, and the spring 31 is supported on the spring supporting disc 7 by the hook pieces 71.
- the large diameter annular belt portion 47 of the contact plate is fit into the outer circumference of the lower cylinder 51 of the pad leg receiver 5, and the pad leg receiver 5 pressed in from the upper portion of the mounting boss 1, whereupon the sliding between the tapers 53 and 12 and opening of the cylinder upper portion of the mounting boss due to the slits 14 enable the pad leg receiver 5 to be set into the mounting boss 1.
- the terminal 46 at the center bottom of the contact plate 4 projects downward from the spring center hole 32.
- the pad leg receiver 5 is held in the state with its engaging face 54 abutting the engagement face 13 of the mounting to boss 1 by the pushup force of the spring 31 via the contact plate 4.
- the base plate 10 of the mounting boss and the electrode plate 20 are aligned so their holes H 10 and H 20 overlap, then are fixed by the screw 2 at a suitable position of the boss plate B.
- the leg projecting engagement portion F 1 of the pad P is then pressed into the pad leg receiver 5.
- the switch can be fixed more securely to the boss plate than in the second embodiment.
- the spring is a diaphragm-like flat spring 31 deformed to a conical shape, it gives a better feel than the coil spring 3 in the second embodiment.
- the horn switch system of the present invention may be used for many types of steering wheel horn mechanisms. It reduces the design limitations of horn switch mechanisms steering wheels and also the design work.
- the unit switch can be used in common for many types of the steering wheel, the number of parts required to be stocked by a manufacturer can be reduced.
- the horn switch mechanism can be pre-assembled, the precision of the contact stroke of the switches rises, facilitating assembly into the steering wheel and enabling automatic assembly. Further, maintenance and administration of parts become easy.
- the pad leg receivers 5 were circular cylinders, but they may also be square cylinders. In short, it is only necessary that the pad leg receiver and spring be concentric.
